3—位含氮官能团取代的羊毛甾醇衍生物—甾醇24—甲基化转移酶抑制剂的合成

本文报道了羊毛甾醇3－酮，3－乙酰基羊毛甾醇，3－肟羊毛甾醇，3α－氨基羊毛甾醇和3β－氨基羊毛甾醇的合成方法，所合成的产物应用薄层色谱（Rf值），气相色谱（RRTc值）和光谱学（红外，质谱，核磁共振氢谱和碳谱）等方法鉴定了它们的结构。

Synthesis and Antiinflammatory Activity of 2 (4 Methoxy benzylidene) 5 aminomethyl Cyclopentanone Derivatives

In this paper, ten new derivatives of 2 (4 methoxybenzylidene) 5 aminomethyl cyclopentanone were designed and synthesized The structures of all these ten title compounds have been confirmed by IR, 1 H NMR and elemental analysis The compounds have been examined for the antiinflammatory activity on carrageenin induced rat paw edema test Through chemical synthesis, we have confirmed that the amino exchange reaction proceeds by an elimination addition mechanism
